I've just finished installing Cacko Rom 1.23 on my C1000 and converting it back to full Japanese.You may ask, why bother when the original ROM is already Japanese ?Well naturally like the rest of the folks here, I wanted the speed improvements in video playback plus the many other drivers and kernel tweaks. Furthermore, it was the only way to get my Sony Clie PEGA-WL100 wifi CF card (actually a rebadged Intel PRO/Wireless 2011B ) to work on the C1000. And lastly, it gave me the opportunity to free up the 33MB of internal memory taken up by the SLJisho dictionary which I`ve outgrown.

For those still unfamiliar with the Zaurus, the language conversion process involves putting back the .qm and lib files from the original Sharp ROM, which can be done by simply installing the Japanese support packages. However, the packages are missing a few files. This brief guide will go through the installation steps and explain how to "manually" add the missing files. It's a straightforward exercise (though admittedly I spent an entire week searching for the solution to the keyboard error) considering the amount of work already done by the Cacko team in compiling the support packages

It goes without saying that you should first backup your PIM data (from /home/zaurus/Applications/dtm )and other personal settings before proceeding. I would also recommend doing a NAND backup (since you NEED to restore to the original Japanese ROM for your Zaurus warranty to remain valid)

(Updated 18-5-2006 to include the C860 guide and optional and previously missing items)

3) Install ZEditor:http://web.mol.ru/~zaurus/feed/zeditor_2.2...glish-1_arm.ipkAssign root privilege to ZEditor, then go to /home/zaurus/Settings/locale.conf.Open the file and change the language to Japanese: Language = jaSave and reboot.You will now be greeted by the familiar Japanese system messages and menus, and most of the applications are now in Japanese.

4) The remaining few applications that are still in English will have to be manually converted.So you will need the files from the original Japanese ROM, which I've consolidated and uploaded here:japanese-support-c1k_&_c860_1.23_supplementary.zip(unzip it on your PC then transfer to Zaurus)

Install TreeExplorerQT:http://web.mol.ru/~zaurus/feed/treeexplorer_1.7.5-1_arm.ipkand use it to copy the unzipped supplementary files into the appropriate directories as follows:(Note: you will also need to set the file permissions manually once they're in place; take reference from the existing files in each directory )

11) Keyboard -- In Japanese input mode, pressing Shift+0 produces mojibake instead of the expected full-width tilde.===================================================================Caution: take special care when editing qpe.sh, as it controls the Qtopia user interface===================================================================Use Zeditor to edit /home/QtPalmtop/qpe.sh as follows:delete the line:export UNICODEMAP="cp866"and replace it with:export UNICODEMAP_JP="open-19970715-ms,cp932,nec-vdc,ibm-vdc,udc"(just copy and paste the line using the included .txt version of this guide)

12) save and exit, then Reboot. Congratulations, you now have full Japanese support on your C1000.note: If your Zaurus starts acting strange, it probably means you've messed up qpe.sh.Simplest way to fix this is to reformat and use the backup from step 10.

4) Install ZEditor:http://web.mol.ru/~zaurus/feed/zeditor_2.2...glish-1_arm.ipkAssign root privilege to ZEditor, then go to /home/zaurus/Settings/locale.conf.Open the file and change the language to Japanese: Language = jaSave and reboot.You will now be greeted by the familiar Japanese system messages and menus, and most of the applications are now in Japanese.

Incorrect files in the package that rokudo supplied (he had C1000 but created a c3100 package as well). Please help.

Perhaps you did not read my introductory post: I created this thread and the guide specifically for C860 and C1000.These are the models I actually own so the packages I created have been tested and I know for certain that they work correctly.

Although I have tried my best to explain what each step of the conversion guide actually does, I have no idea if these steps work the same way with the newer models. And I did not make any packages for the C31000.

btw, forget about the Japanese kernel, it's meant for the earlier Cxx0 models (read post#21 to 28).

I use Cacko 1.23 Japanese on an SL-C3200 without any problems. What I did and what I'd recommend for SL-C3100 users in view of these problems is:

With the Sharp ROM flashed tar the entire root.Flash Cacko with the Japanese kernel.Inspect the japanese-support file and recreate the ipk with the files in it taken from the Sharp ROM, I did this with the SL-C3200 since I saw they differed.Then install the recreated ipk.Then change the language to Japanese, reboot.

My SL-C3200 now works no probs this way, all the input methods and stuff.
